IMPROVEMENT IN HOSPITAL-BEDS.

To whom it may concern:

Be it known that I, ISABELLA WALLER, of Cleveland, inthe county of(Juyahoga and State of Ohio, have invented a new and useful Improvementin Hospital-Beds; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon and being a partof this specification, in which Figure 1 is a perspective view of mybedstead, with the invalid-frame partly raised; and Fig. 2 is a detachedplan view of one of the webs and its hook.

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature of this invention relates to a hospital-bed andelevating-frame, so arranged that the patient may be lifted clear of themattress and sheets without displacing his limbs or otherwisedisturbing, so that the mattress and sheets may be changed withoutannoyance; and it consists in the novel and peculiar construction of thevarious parts, as more fully hereinafter set forth.

In the drawing, A represents a bedstead, with four corner posts, a a aa. B B are two windlasses, one being journaled in the tops of the postsat the head, and the other in the tops of the foot-posts, and eachprovided with a crank, b, by which it may be rotated. Both windlassesare so arranged as to be detachable from the bedstead when not required.On each winch or Windlass is a ratchet, c, with which engages aspring-pawl, d, on the post, to secure the Windlass at any point. O is aframe which just fits within the frame of the bedstead, and, by twoslings, D D, at each end, is connected or suspended from the windlasses,

so that, when theylatter are rotated in the proper direction, the framecan be lifted bodily from. the plane of the bed. E are cloth webs, witha metallic rod, 0, sewed across one end, to engage with pairs of hooksf, disposed on the inner edge of the frame at one side. 0 are similarrods in the other end of such web, which engage with hooks g, which passthrough holes in the other side of the frame, and are threaded on theirouter projecting ends to receive nuts h, by which the webs maybestretched.

The operation of my improvement may be described as follows: A mattressand sheet are laid on the bedstead and on top the web frame, which isthen connected by its slings to the windlasses, when the bed is readyfor the reception of the patient, who lies on the webs. When it isdesired to change the under-bedding, or to introduce a vessel under himfor stooling, the attendants rotate the windlasses, and elevate him withthe frame without changing his position or disturbing him in any degree.By disengaging the pawls from their ratchets, the frame may be asreadily lowered again to the bed. By slacking the nuts on thescrew-hooks, the webs may be removed, one by one, without materiallydisturbin g the patient, and in like manner be replaced, when required.I

What I claim as my invention, and desire to secure by Letters Patent,is-- The combination, with the posts of a bedstead, of the windlasses B,cranks b, pawls d, ratchets c, slings D, frame 0, provided with theadjustable detachable transverse webs E, substantially as and for thepurpose set forth.
